Return to the Sea God.

After serious consideration, Zhou Yi decided to tell Tietie the truth.

"I am not a Heavenly Person."

"My name is Zhou Yi, and like you, I am a human, but I have had similar experiences."

Tietie was actually very happy: "That's great. If it were a god, I'd be too nervous to speak much, but if you are the same kind, we can at least talk more. Right?"

Whether it was being offered as a sacrifice, working as a laborer in an alien world, or losing sense and falling, she maintained a positive and optimistic attitude.

This also influenced Zhou Yi.

Compared to Tietie's troubled fate, his own troubles seemed trivial.

His mood also lightened.

"Zhou Yi, is the world on land still the same as before? Are there mountains and water, rats, and fruits?"

"The natural environment hasn't changed much."

"I'll tell you a secret, cover your ears and you can hear the sound of flowing water."

"That's the sound of blood flowing in your body."

"Sound of blood? Oh, I thought I was the only one who knew that!"

…

"Zhou Yi, do you know Mountain Village? That's my hometown."

"Never heard of it."

"That's what we call it at least, I lived in the mountains there before I was taken by the Divine Servant. If you happen to pass by, could you please help me check on it?"

"Sure."

Zhou Yi hesitated for a moment but still told the truth: "Many years have passed since your time, the village must have changed a lot."

"I know, there is a saying in our place, one day in the sky equals one year on earth. Although I don't know how long it has been, definitely none of them are people I know."

"I just want to tell them. If chosen as a sacrifice, when reaching the heavens, definitely don't talk carelessly, don't interact with others, that way you could live a bit longer."

Tietie said this.

Zhou Yi was silent for a while.

"Okay, I'll keep an eye on the village for you."

"Thank you."

"It's nothing. I also need your help."

"Just ask, don't be too polite."

…

That ended this part of the conversation.

Zhou Yi was about to close his eyes to rest when he suddenly heard Xiao Fu's voice in his mind.

"Da Zhou, Tietie's ability potential is very high."

"Remember what I said? A high-dimensional civilization will transfer part of its civilizational heritage, whether it's cultural, material, or preserved life information, through the Circular Flow secretly to other worlds."

"Even if there are clues, reaching that civilizational heritage is extremely dangerous. As it will be protected and defended in various ways."

"But if we can harness Tietie's ability, it can prevent the protective consciousness from detecting our presence, not triggering alarms or attacks, allowing us to infiltrate those hidden storage points!"

The Reverse Flow suggested excitedly: "We must make good use of this ability."

Zhou Yi said: "We just need to decompress and restore Tietie when needed, right?"

"That process is too cumbersome and time-consuming. Many operations need to be done in an instant."

The Reverse Flow said: "Direct use of Fire Seed Life capability needs building a Fire Civilization, connecting at least 150 Fire Seed Lifes. However, there is a transitional solution, which is to create the Fire Chamber Plate, a Circular Flow device that can hold three Fire Seed Lifes and use their abilities directly through the dial."

"For example, you could directly use mic master's 'BGM Field' or Tietie's 'Forgotten'. The strength and precision are the same as the ability holder's own."

There's such a thing.

Zhou Yi immediately perked up.

He was a bit annoyed: "Why didn't you say this before?"

"The Fire Chamber Plate is more complex and precise than the Fire Transmitter, manufacturing takes time, about a year."

Xiao Fu said: "Once I start making a Circular Flow device, I can't be distracted and talk to you, I must be completely immersed in the manufacturing process. If interrupted, I have to start over."

"There was no need to make it before, but because the 'Forgotten' ability mechanism fits treasure hunting, I also recorded two locations suspected of containing heritage before, so I brought this up, because it's necessary."

Zhou Yi thought wow.

Turns out there were plans already.

"Start making it. I won't interrupt you under any circumstances for a year."

"Then there's no time to delay, I'll start now."

…

The Sea God docked at the pier of Yalong Bay.

Zhou Yi took the opportunity to visit the two mutants in the adjacent cave.

He found that Li Mo and Heavenly Dog were still tirelessly making wares with integrity.

"Chairman."

"This is a new cup we made, it can cool down."

"Isn't it hot in summer? With this cooling cup, it's very refreshing."

Li Mo held up the black cup in his hand.

A cool mist flowed from it.

Zhou Yi took it and felt the handle was very chilly, it was like there was a little refrigerator inside, chilling the air around the cup's mouth.

"What's the principle behind it?"

Li Mo giggled: "It involves inserting ground Bitter Root powder inside and igniting it; this can cool down, complementing the Flame Cup."

Zhou Yi was excited for nothing.

He thought it was some new technological product, but it turned out to be a use of Da Li's patent.

"Chairman, besides consulting Da Li, this cup also contains elements from Heavenly Dog and myself."

Seeing Zhou Yi's displeased face, Li Mo quickly explained: "We thought, if Bitter Root could be made more burn-resistant, it could cool for a longer duration. So, after repeated testing, we added coal, clay extracted from the Dead Sea mud, and other materials, the results were surprisingly good. Mixing Bitter Root, coal, wood dregs, quicklime, and clay in a ratio of 1:1:1:1:6 created the cooling coal."

"This cooling process is not fast, but it is just right for cooling small areas, capable of lowering indoor temperatures to as low as 20 degrees Celsius."

"And most importantly, it consumes very little Bitter Root; one piece of cooling coal can burn for 12 hours. Previously, the same amount of Bitter Root could only burn for 3 minutes, now we've increased the endurance by 240 times!"

The overgrown child said somewhat proudly: "Though it's not some advanced technology, it can significantly reduce our Bitter Root expenses. Earlier, Da Li even mentioned cultivating Bitter Root for several more years. Now we have more than enough! We can continuously use Bitter Root for cooling."

Zhou Yi frowned: "Why wasn't this reported?"

"Because we still wanted to strive for a better ratio, to reduce costs as much as possible, and we also added some natural flame retardants."

Li Mo showed a subtle smile: "However, Heavenly Dog and I consulted quite a few people on this aspect. Cao Dayuan and Yuan Tong were a huge help; they selected suitable clay and found the flame retardants."

"We also thought about placing cooling cups in underground caves, igniting high-density cooling coal, and adding water. Then we'd have ice in summer."

"This has already been proven feasible; we just need to increase the ratio. The underground can maintain a low temperature for a long period, consuming far less than above ground."

"Later, we had 703 assist us, using programs to simulate our cooling coal to rapidly determine precise ratios, and what structure of containers would be most suitable. Underground ice storage and indoor cooling environments differ, so there are many variations."

This made Zhou Yi think.

If the cooling coal technology was truly feasible and mass-producible, ordinary houses could also stay cool in summer.

More importantly, once ice storage facilities are built, many foods could be stored for long periods without spoiling.

Not to mention iced cola! Iced coffee!

Zhou Yi felt a thrill of excitement.

"The detailed blueprints and samples are with 703; you can go and take a look. Here, we are testing some new structures, but actually, the application has largely been finalized by them." Li Mo looked aside: "Heavenly Dog, say something."

The Kobold held back for a moment, then said: "Li Mo is right."

"...Continue."

Zhou Yi quickly returned to Jade City and reached the programmers' container office.

Inside, he didn't see 703, only the programmer Walker.

"Where are the others?"

Walker replied, "Chairman, 703 went to the Tamed Bull Tribe to repair their semi-sophisticated entity. Number Nine went to test data on Hooked Horned Bull movement. The Little Elephant was invited by Mr. Yuan Tong to the dam; they've designed the latest large-scale Desperate Machine and are currently testing it."

The programmers were already shining in their respective fields.

Zhou Yi felt immensely gratified.

"Walker, Li Mo and Heavenly Dog mentioned that the latest blueprints and samples for the cooling cup technology are with you, right?"

"Yes, Chairman."

The humanoid robot rolled on its wheels to the southeast corner.

There was a pile of odd wooden models and various metal devices. It lifted a rectangular wooden box about 1 meter in size and steadily placed it on the work table next to it.

The wooden box was still emitting pale white smoke.

Walker opened the lid, and a gust of cold air floated out.

"This is a cooling box we developed based on the cooling cup."

"Compared to the cup-like device, a box-like structure has larger space and capacity. By fixing the cooling range, energy consumption can be reduced, and the consumption of the cooling fuel can be more directly observed."

The cooling box uses a double-layered wooden board structure, with a large amount of soil filled between the wood layers.

The style is quite primitive and rough.

Zhou Yi was uncertain: "Is the inside filled with ordinary soil?"

"Yes."

Walker explained, "Mr. Chairman, we have tested many common materials. After excluding the extremely expensive composite materials, we found that soil, plant fibers, and wool have the best insulation effects."

"Soil is the easiest to obtain and adjust, and it is also the cheapest."

"There are gaps between the soil particles, which are filled with air, and since air is a poor conductor of heat, the soil can effectively slow down the rate of heat conduction."

"On the other hand, soil contains moisture, which has a high heat capacity, allowing it to absorb and store more heat, leading to slower temperature changes."

"We use soil as the internal insulation layer. Although it looks simple, the effect is not bad. If it is used for too long and the effect weakens, the soil layer can also be easily replaced and removed."

Zhou Yi gradually accepted this somewhat rustic odd device.

As long as it works.

The interior of the cooling box is divided into two layers.

The upper layer is a large space used to store substances that need to be frozen, currently holding a frozen, hard chicken skeleton. Obviously, the effect is good.

The lower layer has a tray rack with four small pieces of honeycomb coal that are lighter in color than normal coal.

"This is our final size of cooling coal, which can be ignited with dry grass and other combustibles."

Walker introduced, "Mix bitter root powder and other materials in proportion, compress them into shape with molds, and dry them to the appropriate hardness for use."

"However, when ignited, some smoke and dust will be produced inside, which will escape through the soil and wood boards. It is best to keep the room ventilated, or to equip it with a dedicated smoke vent, to avoid safety hazards. This part still needs further optimization."

It raised its mechanical arm, pointing towards the four pieces of honeycomb coal.

"Currently, we have two specifications of cooling coal. Number 1 coal is used for refrigeration and can maintain an interior temperature of around 5 degrees Celsius, which is sufficient for regular food preservation. Number 2 coal can achieve freezing temperatures below -18 degrees Celsius, but it also costs a bit more."

Zhou Yi asked it, "How much does this whole set cost?"

"The cooling box is made of simple materials and is cheap to make; the cost is about 200 mushrooms, not much more expensive than a regular wooden box."

"The most expensive part is the cooling coal. The recent coal-producing city is Steel Refining City, where the price of coal balls is 10 mushrooms each. To process them into Number 1 coal, since natural bitter root is plentiful and we are also planting it on a large scale, the average material cost is 15 mushrooms per piece."

"The cooling box needs to consume 2 pieces of cooling coal per day to keep running. So, the daily minimum expense is 30 mushrooms, which sums up to 900 mushrooms a month."

Walker stated, "According to your requirements for the company's products, we need to ensure more people can afford it, this is already the lowest cost under the current scheme, and it cannot be reduced further."

It is currently summertime.

It would be best to deal with the cooling box sooner rather than later.

Zhou Yi immediately called Gong Zheng, Zheng Tao, and Qian Su to come and discuss.
